  4. Bulk Water Supply in Limpopo • The growth points in red are, apart from existing supplies, currently not addressed by either Implementation Ready Studies (IRS) or by constructing of a water resource/services project. • The other growth points are covered with an IRS or a phase of a regional bulk water project is under construction to alleviate the water problem • The water resources and transfer schemes are to support the development of the different growth points in the province.

  5. Bulk Water Supply in Limpopo All Growth Points must have water supply schemes: • A water resource – surface and/or groundwater • A water treatment plant • Pump stations • Regional Bulk – from source to and including bulk reservoir • Internal Bulk– from bulk reservoir outlet to reticulation connection • Reticulation– from internal bulk end to household meter

  6. Bulk Water Supply in Limpopo DWA has constructed many major dams in Limpopo in the past which supply water to people and other users, namely: • Nzhelele, Vondo, Damani, Lupepe-Nwanedi in Vhembe • Middle Letaba, Ebenezer, Tzaneen, Thabina, Tours, Blydepoort in Mopani • Mokolo, Doorndraai, Glen Alpine in Waterberg • Houtrivier, Chuene, Molepo in Capricorn • Vergelegen, Nkadimeng, Piet Gouws, Flag Boshielo in Sekhukhune

  7. Bulk Water Supply in Limpopo DWA is developing the major dams in Limpopo: • Inyaka (now in Mpumalanga) • Nandoni in Vhembe District • Flag Boshielo Raising, and • De Hoop in Sekhukhune District- construction 50% completed • Nwamitwa in Mopani District in planning • Possible dam in Olifants river under investigation

  8. Bulk Water Supply in Limpopo DWA is planning and developing major water transfer schemes in Limpopo from: • Inyaka (now in Mpumalanga) to Acornhoek • Nandoni in Vhembe District to Makhado, Matoks, Giyani, etc • Flag Boshielo to Pruissen at Mokopane • De Hoop in Sekhukhune District to Burgersfort, Tubatse, Lebowakgomo and Polokwane (ORWRDP) • Crocodile river to Lephalale (MCWAP) • Groblersdal to Moutse West

  9. Major Schemes • Olifants River Water Resources Development Project (ORWRDP) • Mokolo & Crocodile Water Augmentation Project (MCWAP) • Groot Letaba Water Augmentation Project (GLeWAP) • Luvuvhu River Government Water Scheme (LRGWS) – Nandoni Distribution Scheme • Water Services Bulk Water Supply in Limpopo

  10. 88m high De Hoop Dam (R3 075 million) on Steelpoort River– Implementation by DWA • Extensive bulk distribution systems (pump stations, balancing dams and pipelines) from De Hoop and Flag Boshielo Dams (R12 981 million) • Implementation by TCTA • Primary water supply in Middle Olifants River catchment area – Regional Bulk and Reticulation (R6 812 million) • Industrial water for mining on eastern limb of Bushveld Igneouscomplex 1. ORWRDP PHASE 2: DESCRIPTION & PURPOSE

  11. 1. ORWRDP (DE HOOP)REGIONAL BULK AND PRIMARY RETICULATION TO HOUSEHOLDFEASIBILITY STUDIES

  12. 1. ORWRDP PHASE 2: SCHEDULE (Subject to availability of funding) • 2A: June 2007 – Mar 2013 • 2B: Jul 2011 – Dec 2013 • 2C: Jul 2011 – June 2013 (Steel Bridge: July 2012) • 2D: Jul 2011 – June 2013 • 2E: April 2012 – March 2014 • 2F: April 2012 – March 2014 • 2G: April 2012 – March 2014 • 2H: Incorporated by March 2013

  13. 1. ORWRDP PHASE 2: PROJECT RISKS & MITIGATION • Level of commitment by mines and municipalities due to effects of ongoing global recession • High social demands • Affordability • High cost of scheme • Reliance on electricity for pumping • Alignment of completion of water resources & services infrastructure • Implement GWW with government funding • Implement WC & DM • Government funding • Step wise implementation within funding constraints • Align with Eskom’s developments • Aligned planning and water supply agreements

  14. Augmented water supply in the Lephalale area to meet the water requirements of the Medupi Power Station, and the future water requirements related to the expected growth in the Lephalale Municipality • Industrial water for possible CTL plant by Sasol • Phase 1 (R2 059 million) includes a new pump station at Mokolo Dam and pipeline to Medupi and Matimba Power Station, Exxaro mine and Lephalale town • Sub-phase 2A (R13 455 million): Abstraction works at Vlieëpoort and BDS to Steenbokpan and Lephalale areas • Sub-phase 2B (R1 590 million): Duplication of BDS • Social/Commercial portion on/off-budget • TCTA implementing agent • Regional Bulk and Reticulation (R 330 million) 2. MCWAP: DESCRIPTION & PURPOSE

  15. 2. MCWAP: SCHEDULE (Subject to environmental authorisation and Integrated Resource Plan (IRP) for electricity) • MCWAP-1: July 2011 – July 2013 • MCWAP-2A: Jan 2013 – Dec 2016 • MCWAP-2B and further phases: Depends on IRP and investment decisions by the private sector and other stakeholders

  16. 2. MCWAP-1 AND 2A: PROJECT RISKS & MITIGATION • Likelihood of appeals against environmental authorisation high • Very tight construction programme • Affordability of water by social users • Delayed IRP for electricity • High dependence on single resource, i.e. Mokolo Dam • Concerted efforts to deal swiftly with possible appeals • Efficient implementation strategies and contract management • Government funding • Co-operative governance • Investigate and implement additional and alternatives sources

  17. 3. GLeWAP: DESCRIPTION & PURPOSE • 36m high Nwamitwa Dam (R1 262 million) on Groot Letaba River – Implementation by DWA • 3m raising of Tzaneen Dam (R84 million) • Regional Bulk Water supply (R410 million) • Provide primary water requirements in Mopani District • To implement the preliminary Reserve in compliance with the National Water Act • To stabilise the assurance of supply to the existing irrigation farming • To improve water availability for the establishment of resource-poor irrigation farmers

  28. Bulk Water Supply in Limpopo FUNDING • The dams are funded by National Treasury • Funds not so easily available for RBIG and Reticulation through MIG Example: • De Hoop is funded at R3 billion by National Treasury. • Bulk Distribution and reticulation to Households require R20 billion. • R1.2 billion is available from 2007 to 2013 through RBIG and MIG. • Shortfall of R18.8 billion is needed to serve 2 million people and mining. • Mines and Municipalities not in a position to sign off take agreements with DWA.

  29. Bulk Water Supply in Limpopo Example: • RBIG is funding a pipe line from Steelbridge to Jane Furse – 70% completed • Sekhukhune DM with MIG is on tender for WTW at Steelbridge and 10 Megaliter reservoir at Jane Furse for completion July 2012. • DWA has to do Phase 2C pipe from De Hoop Dam to Steelbridge for completion July 2012 depending on funding from National Treasury.
